My environment is Macbook pro : Xcode 9.1 : macOS High Sierra

I have finished “Modern OpenGL” course.

So, I have prepared all files and started to learn the course “OpenGL Game Rendering Tutorial”. But, one error ocurred…

In the timing.cpp, the error is “No viable conversion from ‘time_point’…….”

I couldn’t solve this problem. Please give me some advice.

I prepared all files from github.
